    Default WiMaX LOS & NLOS By SR TELECOM

    WiMAX Technology
    LOS and NLOS Environments

    While many technologies currently available for fixed broadband wireless can only
    provide line of sight (LOS) coverage, the technology behind WiMAX has been
    optimized to provide excellent non line of sight (NLOS) coverage. WiMAX’s
    advanced technology provides the best of both worlds – large coverage distances
    of up to 50 kilometers under LOS conditions and typical cell radii of up to 5
    miles/8 km under NLOS conditions.
